` Application filed July 17,

To all whom t may concern.'

Be it known that l, CHARLES; E. Linn BARGER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Gil Cups, of which the following is a specification.

This invention relates to oil cups to be used for lubricating bearings, springs, and various other portions of machinery, auton mobiles and the like. lt has for its object the production of a suitable oil cup and suitable mechanism to be used in connection with the cup for very eectively applying the oil, and particularly the object is to pro* vide an oil cup which may be very conveniently filled with oil and tightly closed against dust or other objectionable substances and which has mechanism connected therewith adapted to, and very conveniently operated for, forcing the oil with suitable pressure into the bearings. Other objects of the invention will be apparent from a consideration of the accompanying drawings and the following description thereof.

Of the drawings, Fig. 1 is an elevation of an ordinary type of oil cup, and AFig. 2 is a central, vertical, section of the same, which embodies the features of my invention.

Gil cups indicated by the drawings herewith, in general, are similar to the ordinary forms of oil cups. They are arranged to receive and store a suitable supply of oil in the cup 10, the cup being screwed into the bearings or other portions of the mechanism by means of the oil outlet shank 11. In order to produce a suitable pressure on the oil to force it through the outlet and into the bearings, I provide, within the cup, a tube 12, which is fixed in any suitable manner in the bore of the shank 11, and which projects upwardly into the cup chamber 13 a suitable distance, depending more or less on the particular use of the cup. Within the tube 12 is slidably mounted a suitable pin in the nature of a piston 14, and a suitable opening 15 is formed in the tube 12 near the lower end of the cup chamber 18, so that when the pin is raised with its lower end above the opening, the oil will flow into the bore of the tube and shank and into the bearing; and when the pin is pressed downwardly the oil will be forced, with such pressure as may be arranged for, into the bearing.

The means which I provide for elevating 1920. Serial No. 397,078.

the piston comprises ears 19 fixed to the inner side of the cup cover 1li, and any suitable forni of link mechanism connects the ears with the upper end of the piston. In

any resilient means may be provided for such purpose, but l prefer for the purpose a coil spring 18 which is associated with the hinge of the cover and which is arranged, in an ordinary manner, to force the cover 16 downwardly when it is released. spring obviously, in forcing the lid downwardly, will also force the pin downwardly against the oil in the bore of the tube 12 and the shank 11. In order to prevent the lid being opened too far l provide lugs 20 proliecting downwardly from the ears 21 of the hinge of the lid, the lugs 2O being arranged to strike against the respective bosses 22 which are fixed to the outer surface of the cup. By this arrangement it will be seen that the cover may be raised so far as is desirable in order to insert oil in the cup, but is prevented from raising to such a height that the pin 14 will be pulled entirely out of the tube 12 or will be forced higher than is desired to properly supply the oil.

l claim as my invention:

1. An oil cup having a casing with a cover and an oil outlet, a tube mounted in said casing and having a bore connecting with said outlet, a pin slidably mounted in the bore of said tube, and means fixed to said cap for sliding said pin in said tube.

2. An oil cup having a casing with a cover and an oil outlet, a tube mounted in said casing and having a bore connecting with said outlet, a pin slidably mounted in the bore of said tube and means xed to said cap for sliding said pin in said tube, said tube havinglan opening in the lower portion of its wal 3. An oil cup having a casing with a cover and an oil outlet, a tube mounted in said casing and having a bore connecting with said outlet, a pin slidably mounted in the bore of said tube, means fixed to said cap for sliding said pin in said tube, and resilient nieans tending to force said pin inwardly in said tube when the pin has been partly withdrawn and the withdrawing means have been released.

4L. An oil cup having a tubular oil outlet, a cover for said cup, resilient ineans tending to hold said cover closed, a pin slidably positioned in said outlet, and nieans operatively connecting said pin with said @over whereby said Vpin will be withdrawn somewhat 'from said outlet when said @over is raised.

5. An oil eup hating an. oil outlet, a cover for said cup, resilient means tending to hold said cover closed, a pin slidably positioned in said outlet, and .means operatively connecting said pin with said eover whereby said pin will be withdrawn somewhat from said outlet when said cover is raised, said outlet being opened by the withdrawal of said pin.

6. An oil cup having an oil outlet, a cover for said cup, resilient means tending to hold said cover closed, a pin slidably positioned in said outlet, means operatively connecting said pin with saideover whereby said pin willbe Withdrawn somewhat from said outlet when said cover is raised, and means limiting the distance said pin will be Withdrawn by raising said cover. Y Y

7. An oil @up having an oil outlet, a cover for said cup, resilient ineans tending` to hold said erover closed, a pin slidably positioned in said outlet, and means operatively oonneeting said pin with'said eover whereby said pin `will be withdrawn somewhat from said outlet when said cover isf raised, said means comprising a link pivoted to the inner side of said cover and also pivoted to said pin.
